DETAILED DESCRIPTION

In the following detailed description, reference is made to theaccompanying drawings, which form a part hereof. In the drawings,similar symbols typically identify similar components, unless contextdictates otherwise. The illustrative embodiments described in thedetailed description, drawings, and claims are not meant to be limiting.Other embodiments may be utilized, and other changes may be made,without departing from the spirit or scope of the subject matterpresented here. It will be readily understood that the aspects of thepresent disclosure, as generally described herein, and illustrated inthe figures, can be arranged, substituted, combined, and designed in awide variety of different configurations, all of which are explicitlycontemplated and made part of this disclosure.

An HCI cluster is one or more virtualized workloads (one or more virtualmachines, containers, etc.) that run services/applications/operatingsystems by using storage and compute resources of one or more nodes(e.g., computers, physical devices) which are virtualized through ahypervisor (e.g., host). Thus, the cluster refers to the cluster ofphysical nodes as well as the cluster of workloads. The cluster can belocated in one node, distributed across multiple nodes in one datacenter (on-premises) or cloud, or distributed across multiple datacenters, multiple clouds or data center-cloud hybrid. At least one ofthe workloads (e.g., a controller virtual machine or container) in thecluster runs core services that manages and maintains the cluster,including a cluster manager, a health/wellness check manager, an I/Ostorage manager, and the like. In some embodiments, a workload managesmultiple clusters. As part of the health check, an HCI cluster employsedge processing units 140 to collect and process data about the nodesand services running on the clusters and alert customers/users of theclusters when performance issues (e.g., excessive latency, lack ofresources, non-availability, lack of fault tolerance, lack ofreplication, lack of consistency, one or more nodes are down, need forupgrade, etc.) arise.

One problem is that the core services are typically packaged as a bundle(like an operating system) and upgrading the entire bundle of servicesis very slow, disruptive, and resource intensive. In particular, edgeprocessing units need configuration updates when they generate falsepositives (e.g., incorrect alerts/notifications) regarding theperformance of the clusters. What is needed is a way to strategicallyupdate the configuration of specific services of specific clusterswithout having to upgrade the version of bundled services.

The present disclosure is generally directed to a telemetry platform forHCI clusters with intelligent edge processing units. In someembodiments, the system dynamically pushes new configurations from acloud server to edge processing systems running in a virtualizedhyper-converged environment in a canary manner and has the capability torollback these configurations dynamically from the cloud server. In anexemplary embodiment, a cloud server collects service data from variousproducts and deployments across datacenters and different environmentsof a virtualized network. The system executing on the virtualizednetwork may run edge processing units at edges of the network to processdata upfront and send summarized data to the cloud server.Advantageously, the dynamic edge systems may update configurations onthe edge to stop false positives, to add new signatures, or to changethe configuration of existing signatures. Moreover, edge processingunits may collect meaningful data while at the same time limiting theamount of data collected and send to the cloud server. In this manner,processing of data can be maintained closer to where the data isgenerated, reducing the amount of data communicated to the cloud serverand providing flexibility to consume processing results and outputs onthe edge device along with the clout.

According to an exemplary embodiment, each edge processing unit has itsown configuration which is used by the edge processing system to controlthe behavior of the intelligent edge device in a virtualized,hyper-converged environment. These configurations may control the amountof data processed by the intelligent edge device, processing logic andrules run on the edge device, frequency of the processing rules, andalso the amount of processed data sent to the cloud server.

FIG. 1 illustrates a system 100 including an edge network side 110 and aserver side 120. The edge network side (e.g., edge side, edge, edgesystem, client side, etc.) 110 includes one or more HCI (hyper-convergedinfrastructure) clusters 130 and one or more collector frameworkservices (CFS) 150. The server side (e.g., server, cloud, cloud side,cloud server, etc.) 120 includes a discovery service 160, a userinterface 170, and a cloud control plane 180. The edge network side 110and the server side 120 are in communication. The HCI clusters 130include edge processing units 140, and the CFS 150 receives operationaldata (e.g., logs/configurations/metrics) of the HCI clusters 130 fromthe edge processing units 140. In some embodiments, the edge processingunits 140 and the CFS 150 are services running on the HCI clusters 130.The CFS 150 can generate health/wellness/state/processed data (e.g.,monitoring data, summary of configurations, alerts, summary of metrics,events, summary of logs, blobs) based on the operational data and sendthe health data to the server side 120 for further processing, storage,and/or other operations. Further, the CFS 150 and/or the server side 120may identify when more or different health data is needed and when falsepositives (e.g., an alert/indication of an issue/problem that does notexist) are received. In some embodiments, there is one of the CFS 150corresponding to every one of the HCI clusters 130 and each of the CFS150 is coupled between its corresponding HCI cluster 130 and the serverside 120. In some, embodiments, each of the CFS 150 runs on itscorresponding HCI cluster 130.

The server side 120 can be connected to a plurality of edge networksides such as the edge network side 110. Each edge network side sendshealth data of its HCI clusters 130 to the server side 120 using atelemetry platform. The health data is analyzed by the discovery service160 at the server side 120. The health data can be analyzed for multiplepurposes, one of which is to detect any false positives generated by anyof the edge processing units 140. Once a false positive is detected bythe discovery service 160, the cloud control plane 180 at the serverside 120 automatically defines a new configuration.

FIG. 2 illustrates an exemplary edge network side 110, including devices230 a, services 230 b, and external services 230 c. The devices (e.g.,edge devices) 230 a can include physical nodes of the clusters 130 orphysical components thereof. The services 230 b may include servicesrunning as part of one or more virtualized workloads that run on top ofa hypervisor connecting the workloads to resources of a cluster ofphysical nodes. The services 230 b may include a cluster manager, acluster health check, a storage I/O (input/output) manager, a concurrentprocessing (e.g., map-reduce) manager, a cluster configuration manager,an object storage service, etc. Some of the services 230 b may bepackaged as a bundle of core services (e.g., scripts) that may behavesimilar to operating system services. The external services 230 c mayinclude services that interact with services 230 b. The devices 230 a,services 230 b, external services 230 c are collectively referred to asHCI clusters 130.

The edge processing units 140 are in communication with devices 230 a,services 230 b and include log processor 240 a, config (configuration)processor 240 b, metric processor 240 c, and the collector 240 d. Thelog processor 240 a may operate on logs generated from the services 230b (e.g., a user management request coming on a cluster), aggregate thelogs, and summarize any issues, e.g., by correlating the logs with otherdata/metrics/configurations on the system. The config processor 240 bmay operate on configurations of the HCI clusters 130 and summarize anyissues. For example, the config processor 240 b may detect that acluster is configured with 20 MB storage instead of 20 GB storage, orthat some VMs (virtual machines) are not protected (e.g., not enoughreplication factor or fault tolerance). The metric processor 240 c mayoperate on metrics of the HCI clusters 130. The collector 240 d is incommunication with the log processor 240 a, the config processor 240 b,and the metric processor 240 c. The collector 240 d may aggregate theirrespective logs, configs, and metrics, define the frequency ofcollection, how much to aggregate, and send (e.g., publishes, pushes)the aggregated/raw data to the server side 120 (via the CFS 150).

The CFS 150 is in communication with the collector 240 d. The CFS 150may instruct one or more edge processing units 240 to change theconfiguration they have. Such an instruction can result from detectingerrors/issues/events, identifying an upgrade need, identifying a statechange such as an increase in nodes or a change in a hypervisor type, orany of a variety of other triggers to change the configuration. In atleast one embodiment, edge processing units 140 collect data from theHCI clusters 130 and the CFS 150 identifies false positives from thecollected data. False positives from the data collect can be a triggerfor changing the configuration of an edge processing units 140. The CFS150 can add or modify existing rules used by the edge processing units240 to correct for errors and false positives. The edge network side 110includes a database 260 in communication with the CFS 150. The database260 can store data collected/received by the CFS 150. The edge networkside 110 includes one or more filtering service 270. In someembodiments, each node includes its own filtering service 270. Each ofthe filtering services 270 can filter configuration updates received orgenerated at the CFS 150 based on whether the configuration updatesapply to (e.g., match with the parameters of) a node corresponding tothe particular filtering service 270.

The edge network side 110 (e.g., CFS 150 or the edge processing units140) or the server side 120 can determine that an edge processing unit140 configuration update is needed (e.g., more data is needed from theHCI clusters 130 than is collected by default). In some embodiments, theCFS 150 detects a state change (e.g., configuration state change, event)in the corresponding HCI cluster 130. For example, the configurationstate changes if a new node gets added to the HCI cluster 130. Also, theconfiguration state changes if a hypervisor or a service gets upgradedor changes vendors. When the state changes, the edge processing units140 (and/or in some cases, the devices 230 a and/or services 230 b) mayreceive a configuration update from the CFS 150 (e.g., without actionfrom the cloud). For example, if a hypervisor vendor changes, theconfiguration update may change the frequency of a process/check that isrunning on the edge. In some embodiments, the server side 120 processesdata collected from the CFS 150, generates a configuration update forthe edge processing units 140, and sends the configuration update to theCFS 150.

Once a determination for a configuration update is made, in someembodiments, the edge network side 110 selects a configuration updatecorresponding to the new configuration state. In some embodiments, whichconfiguration update to select is determined by override configurationrules. In some embodiments, a first one or more override configurationrules are part of the HCI cluster 130 release/base package, a second oneor more override configuration rules are sent to the CFS 150 by theserver side 120, and a third one or more override configuration rulesare sent to the CFS 150 by a user/administrator. In some embodiments,the override configuration rules from the various sources conflict witheach other. In some embodiments, the CFS 150 merges/resolves theconflicting override configuration rules (referred to as “merge logic”).The CFS 150 may defer to the server side 120 rules. For example, a cloudconfiguration request may indicate to override irrespective of therelease package rules, or may indicate not to override if there is anyconflict. The CFS 150 may implement the most conservative rule (e.g.,the rule that results in more data collected). For example, each of theconfiguration rules may specify a frequency for collecting data on theedge, and the CFS 150 may select the highest specified frequency for theconfiguration update.

In some embodiments, as part of the update, the edge network side 110changes or increases the type of data collected or the frequency of thedata collected by the edge processing units 140 and from the clusters130. The edge network side can 110 determine the subset of edgeprocessing units 140 to apply the update config to. The edge networkside can 110 determine whether to configuration update is time bound,and if so, what the duration of the configuration update is. The edgenetwork side can 110 determine whether and when to rollback changes. Theedge network side 110 can determine the version of the configurationupdate.

In some embodiments, the edge network side 110 receives an updatedconfiguration from the server side 120. In some embodiments, the edgenetwork side 110 decides or controls some of the aspects of the configupdate (e.g., whether to rollback, whether the update is timebound,canary deployment, etc.). In some embodiments, the server side 120decides or controls those aspects of the config update.

As described above, the edge processing units 240 use one or moreconfigurations (e.g., edge processing unit configurations, etc.). Theconfigurations may determine what information (e.g., data,configurations/logs/metrics) to collect, where to collect theinformation from, how to collect the information, how granular tocollect this information, when to collect the information, how often tocollect the information, when and where to push the processedinformation. As part of the cluster services, the edge processing unit140 specific configuration default may be included. To make thetelemetry collection more intelligent, edge processing units 140 mayreceive events which trigger the edge processing units 140 to act smart.

The server side 120 can push new configurations based on the calculatedhealth of the cluster/service or the state of the cluster/service orsome external events which influence these configuration setting. Forexample, if the cluster has an open SFDC (sales force dot com)case/ticket created which is an external state triggered, then theserver side 120 can trigger the edge processing units 140 to startcollecting more granular metric information. The server side 120 canreset the state to normal when the SDFC case is closed and the serverside 120 verifies that the problem no longer exists after the fix. Ifthe cluster has an open SFDC case regarding performance of coreservices, the server side 120 can trigger the edge processing units 140to start collecting more granular information and extra information ofthe cluster for the specified time bound. If there is a security issuedetected for the cluster on the server side 120, the server side 120 cantrigger the edge processing units 140 to make changes to what iscollected.

The edge processing units 140 at the edge network side (e.g., running inthe cluster) can increase and decrease the metric frequency from a firsttime period (e.g., 15 minutes) to a second time period (e.g., 5 minutes)when the cluster health is below a predetermined threshold (e.g., whenan alert is raised). This can be indicated in the user interface (e.g.,cloud portal) 170 by displaying a red color in a visual element, or thelike. The edge processing units 140 can revert to the first time periodonce the cluster health is above the predetermined threshold (e.g., whenthe issue is resolved). This can be indicated in the user interface 170by displaying a green color in a visual element, or the like. Thus, thecluster health can be visually indicated by a color.

FIG. 3 illustrates a server side 120 of a network in the virtualcomputing system of FIG. 1 . The server side 120 includes a serverendpoint 310 and a data processing pipeline 320 in communication withthe server endpoint 310. The data processing pipeline 320 may receiveincoming data, perform schema validation, convert data into JSONstreams, and persist all incoming data receives from different devicesand services.

The server side 120 includes a data repository (e.g., data lake,database, etc.) 130. In some embodiments, the ingested/received datafrom the data processing pipeline 320 is stored in the data repository330. The discovery service 160 may perform analytics on the data in thedata repository 330. The cloud control plane 180 may receive the outputof the discovery service 160. The discovery service 160 may sendnotifications (e.g., email, slack) to the user interface 170 andautomatically create or recommend creating open tickets (e.g., in anissue tracking service).

FIG. 4 illustrates the cloud control plane 180, in accordance with someembodiments. The cloud control plane 180 includes a configuration updateprocessor 410, an original configuration database 420, a desiredconfiguration database 422, a requests database 424, and a filteringservice 430. Once a state change or an issue (e.g., false positive) isdetected by the discovery service 160, the cloud control plane 180 atthe server side 120 may automatically define a new configuration totweak the existing configuration of the edge processing units 140 andadd/modify existing rules used by the edge processing units 140 toupdate the existing edge processing units 140. The filtering service 430may filter the edge processing units 140 to a subset that willreceive/apply the update, via the CFS 150 (which can, additionally, oralternatively, have its own filtering service). In some embodiments, thenew configurations are stored in the desired configuration database 422.

In an exemplary embodiment, as part of defining a new configuration, theserver side 120 (e.g., the cloud control plane 180) can filter for theenvironments where a configuration has to be updated. Statechanges/issues/false positives might be impacted on some of the specificcluster/node environments based on the nature of the issue. The serverside 120 may filter out and isolate the impacted edge environments wherea state change/issue/false positive might have occurred. The server side120 may send the configuration updates to edge processing units 140 forsome of the filtered environments across all products and across allhybrid deployments on edge.

In some embodiments, to be able to get the configuration updates fromthe cloud, the server side 120 hosts a pub-sub (publish-subscribe)system 360 as part of its data processing pipeline 320, or in someembodiments, the cloud control plane 180. In some embodiments the serverside 120 receives or generates a request or command to update theconfiguration of the edge processing system based on values of filterparameters (e.g., filter parameters that filter clusters based on theconfiguration state). The request to update may be published to a streamon the pub-sub system. Each client (e.g., each of the HCI clusters 130)may subscribe to particular streams based on the current state of theclient.

In some embodiments, supported filter parameters include a clusterhealth check version (client version), hypervisor type, hypervisorversion, a number of nodes, platform models, hardware type, a coreservices version, BIOS (basic input/output system) version, firmwareversion, LCM (life cycle manager) version. The pub-sub system 360 maypush config update requests for the clusters 130 or the edge processingunits 140 corresponding to the clusters 130 based on the current stateof the system represented by a complex SQL. Script execution can happeneither on the client or the server.

This kind of dynamic filtering mechanism can be implemented with serverside filtering, edge filtering, dynamic filtering based on a script runon edge, or filtering based on data received from the edge. Server sidefiltering: when the edge system subscribes to receive the configurationupdates, it can publish some of its current state to the pub-sub server.Based on this state, the pub-sub system 360 may determine the streams towhich a client subscribes to. The pub-sub system/platform/server 360 orthe filtering service 430 may create the streams to support the serverside filtering. The pub-sub server 360 or the filtering service 430 mayprovide the list of subscriptions/streams based on the client's currentstate at any given point of time. For example, any cluster having firsttype hypervisor vendors subscribe to a first stream. When configurationupdates are ready for that hypervisor vendor type (e.g., the edgeprocessing units 140 of the clusters having that hypervisor vendortype), the pub-sub system 360 may publish the configuration update onthat stream. Whenever the current state of the system is changed, theclient may get a notification and it re-publishes its state, and thepub-sub server 360 or the filtering service 430 may return a new list ofstreams to which it subscribes to. Thus, the pub-sub server or thefiltering service 430 can maintain a mapping of configuration state tostreams.

When a new cluster comes up, the new client may publish its currentstate. Based on the current values of the filtering parameters, theserver may return the list of streams that the client can subscribe to.The client (e.g., the CFS 150) may get the desired configuration of theedge subsystems (e.g., the edge processing units 140 corresponding tothe CFS 150) after the filter has been applied on the server side andthe edge subsystems are updated to use the desired configuration. Theedge system may keep a watch on the hyper-converged edge system to getnotified if the state of the system is changed. Whenever the state isupdated, the client may re-publish the current values to the server andupdates its list of subscriptions. Since the current state of the systemis changed, the client can revert the configuration updates it receivedpreviously since those updates may no longer be applicable. At thispoint, the client may get a new desired configuration for the subsystem.The edge subsystem can be updated to use the new desired configuration.

In some embodiments, the edge side filtering (e.g., client sidefiltering) is applied dynamically on the edge. In some embodiments,server side filters have first state parameters (e.g., server sidefilter parameters) and edge side filters have second state parameters(e.g., client side filter parameters). Once the client (e.g., cluster ornode) receives the configuration update from the server, it may checkfor edge filtering parameters and apply the update only if the values ofthe edge filtering parameters match with parameters of the configurationupdate. One reason to do edge side filtering is that there are manystreams/filtering parameters (e.g., cluster management service version,cluster health check version, number of nodes), and creating streams forevery filtering parameter on the server side 120 may be a unacceptablylarge resource overhead for the server side 120. Thus, the system 100can be optimized by applying some filtering on server side 120 and somefiltering on edge network side 110.

In some embodiments, at each node of the cluster, a filtering service270 determines what is the current configuration state for that node andwhat are the configuration updates that the CFS 150 received from theserver side 120. In some embodiments, the desired configuration isreceived by the edge network side 110 after the server side 120 filterhas been applied. This configuration may include the delta of thedesired configuration for various values of edge filtering parameters.

The config client (e.g., the CFS 150) may store the desiredconfiguration in a DB (database) on the edge. The desired configurationmay have a priority assigned in case of conflicts while applying variousfilters. The filtering service 270 for each node may identify theapplicable desired configuration based on the current values of edgeparameters. The filtering service 270 may parse/traverse the list ofdesired configurations (e.g., stored in the edge database), e.g.,sequentially, in order of priority, or in order of time thatconfiguration was created/stored. The filtering service 270 may applythe desired configuration based on the current values of the edgefiltering parameters for that node.

An example of parsing is included herein. A request may include pairs offilters and new configuration states, in order of priority. For example,a first filter is cluster management service version <5.10, a first newstate is to update collection frequency to 15 minutes, a second filteris health check service version=3.9, a second new state is to not raisean alert, a third filter is hypervisor=first-type, and a third new stateis to update collection frequency to 15 minutes in which the firstfilter has a higher priority than the second filter, and the secondfilter has a higher priority than the third filter. On the edge side, afirst cluster satisfied all the filters (first, second, and third).Then, the first cluster's final state will be to not raise an alert andto update collection frequency to 15 minutes.

The config client and/or the filtering service 270 at each node, as wellas the filtering service 430, can maintain the complete config updateslist it receives from the cloud, along with all edge filters. In someembodiments, both the server side filtering and the edge side filteringfeedback to the config update processor 410 information about theconfiguration updates, such as to which clusters each of theconfiguration updates are applicable. The config client may keep a watchon the edge system to get notified when any of the edge filteringparameters are changed. Whenever an edge filtering parameter is changed,the config client may re-apply the config updates. The config client maydetermine the config updates based on the new values of the edgefiltering parameters. In some embodiments, the config client may revertthe config updates/deltas it made because of the previous state of thesystem.

The above mechanisms may work for any of the filter parameters which thesystem 100 knows about. There may be a need to support filteringdynamically based on a script which is run on edge. Along with theconfig updates, the edge may receive a script which needs to be executedto determine if the system is applicable after applying some complexfiltering logic. The config client may initiate a watch on the currentstate of the edge system, and the config client can re-evaluate thescript if any of the values of the current parameters change. This canenable the client to dynamically receive the filtering logic and run theprocessing on the edge and apply the appropriate config updates.

Filtering may be applied on the cloud based on the current state of eachedge subsystem which is collected through the edge processing units 140.In some embodiments, the filtering applied on the cloud has a dependencyon the data being collected, streamed, and processed in the dataprocessing pipeline in the server side 120 before this evaluation can bedone.

Thus, the system may enable supporting the configuration not only basedon client version but also any other filtering parameters which arepredefined as well as might be added dynamically (both on server andedge) in a virtualized hyper-converged environment.

Referring to FIG. 3 , in an exemplary embodiment, the server side 120provides a variety of capabilities (e.g., in addition to filtering).First, the server side 120 (e.g., the cloud control plane 180) canprovide canary deployments of configuration changes. A canarydeployment, or deployment to a subset, may control a sudden impact ofthe configuration change and test out the changes. A server at theserver side 120 may support canary deployments for the configurationchanges. The server side 120 may provide auditing capabilities of theconfiguration changes. Depending on the embodiment or the selectedcontrol, each configuration change can be audited per cluster and alsofor the applicable filters.

The user interface 170 may provide customer facing controls toenable/disable the configuration changes. The server side 120 mayprovide versioning of the configuration updates. The server side 120 mayprovide rollback capabilities for the config update requests. In casethe configuration update request introduced any regressions, the serverside 120 can roll back the changes, including rollback on the edge androllback on the cloud.

The server side 120 may provide time bound configuration updates. Inscenarios where the plane 190 detects an issue on the cloud anddetermines that extra data is to be collected until the issue isresolved, the server side 120 can trigger a time bound configurationupdate for the edge processing units 140. Such a configuration cancontrol the time until the configuration update would be valid.

Referring to FIG. 4 , the cloud control plane 180 includes a remotecommand controller (RCC) 440. In some embodiments, the RCC server 440exposes an API (application programming interface) which is called bythe discovery service 160 to collect diagnostic information from thecluster. This can be used to run any commands on the cluster. The RCCserver 440 may create the request and store it in a DB. The CFS 150 maypoll the RCC server 440 every predetermined time period (e.g., 2minutes) to check if any new request is available for the cluster. Incase a new request exists, the RCC server 440 may send the request tothe CFS 150. The CFS 150 may send this request to the edge processingunit 140 which executes the required command(s). A command output may besent to RCC server 440 using HTTP multipart.

In an exemplary embodiment, the server side 120 (e.g., the RCC 440and/or the user interface 170) can send commands to the edge networkside 110. There are use cases in which a user at the user interface 170(e.g., administrator/site reliability engineer/support team) wants toget some extra information from the edge for debugging andtroubleshooting purposes which the user can use to resolve the customerissues faster. Use cases include running commands from cloud with somedynamic arguments to debug any open issues, running commands to collectextra data at any given time to help in better detection of issues, andrunning commands from cloud to take any remediation actions on the edge.

In some embodiments, the server side 120 provides a CLI (command lineinterface) like interface (e.g., in the RCC server 440 and/or the userinterface 170) to be able to execute the commands on the virtualizedhyper-converged edge systems running in hybrid cloud environments. Theinterface can define some dynamic arguments to the command based on thecurrent use cases. The interface can pass any shell commands withpiping, etc.

A response to the command, including command outputs, may be sent to theRCC server 440 and/or the user interface 170. In some embodiments, theoutput may be a blob (binary, large object). The user (or the RCC server440 and/or the user interface 170 based on instructions of the user) maydetermine whether the command output is to be parsed at the edge networkside 110 or at the server side 120 (e.g., the data processing pipeline,the discovery service or the RCC server 440). An indication of where toparse the command output may be included in the command. In someembodiments, if the user needs a raw output, the server side 120 canparse the command outputs along with getting the raw output. This isneeded to be able to run downstream analytics on top of the commandoutputs. In some embodiments, if the user only wants schematized output,or if the user or server side 120 determines that less resources shouldbe consumed on the server, then the parsing can be achieved by pushingthe parsing templates/plugin to the edge dynamically and parse thecommand outputs on edge. Parsing can be achieved by collecting the rawoutput from edge and enable a parsing template/plugin on cloud. Theinterface provides controls to be able to inject the data back into thedata pipeline for further processing.

The interface can send the outputs based on the size of the commandoutput/data. Each node (e.g., or service, bundle of services, etc.)independently runs the command and is responsible to send its outputsindependently. In some embodiments, the transmission of the commandoutput is based on the size of the data/output produced by the commandon each node. In some embodiments, the node can send the output as oneor more resumable chunked file uploads if the output is bigger than apredefined limit, or as one file upload (e.g., an HTTP request packet)to the server if the output is smaller than the predefined limit. Thiscapability may offer each node to operate independently and handles anyscenarios in which a bursty output is produced by the command on aparticular node at any given time. This also enables the edge systems tobe able to manage the life cycle of the outputs on each node.

The interface can add dynamic timeouts to the command execution forvarious use cases. For example, a node (or services on the node) istemporarily down/off/unavailable. The interface may run the command ifthe node is restarting or is temporarily down. In some embodiments, anode (or services on the node) is permanently down. The interface maynot wait for a long duration for the node to come back up. In someembodiments, a few of the nodes in the cluster have intermittent orpermanent connectivity issues to the cloud. In some embodiments, thecluster has intermittent or permanent connectivity issues to the cloud.

Thus, the interface may run the commands in the distributed mannerwithout depending on any of the services. The command executionframework may work even if most of the other services are down. Theinterface may run commands when upgrades in progress. The interface canhandle any intermittent/permanent node failures. The interface may runthe commands dynamically with dynamic parameters in a hyper-convergedvirtualized hybrid environment. The interface may run the commands in adistributed environment, handling node failures (temporary orpermanent), and handling any on-going upgrade/maintenance activities.The interface may run the commands in non-homogenous distributedenvironments and also run the commands on host. The interface maycontrol the parsing of the commands to be done on edge or on cloud. Theinterface may send the parsing template/plugin dynamically to the edgeto enable parsing and drop some data from the command output if it's notneeded. The interface is may dynamically send the outputs per nodeindependently, based on the size of the output, and dynamically sendingthe outputs as chunked file uploads or sending it as an HTTP request.

While the foregoing description describes the server side 120 asperforming some of the described operations, the CFS 150 can performmany of the same operations for the HCI clusters 130 and/or the edgeprocessing units 140.

Referring to FIG. 3 , in some embodiments, the server at the server side120 e.g., the discovery service 160 and/or the cloud control plane 180)detects whether issues exist. In some embodiments, issues include that anode, service, or cluster is temporarily or permanently unavailable,that a service, device, or hypervisor upgrade is needed, thatperformance (e.g., I/O per second, number of I/O, CPU usage) issub-optimal, that data is not sufficiently protected (e.g., replicationfactor or fault tolerance is too low), that false positives are beingreported by the edge processing units 140, etc. Issues may exist in somestate of the HCI clusters 130 or edge processing units 140. Based ondata collected from multiple products in hyper-converged environments onthe server, the server (e.g., the discovery service 160) may runanalytics to detect any issue in the edge network side 110. The servercan collect a subset of metrics and configuration information from theHCI clusters 130. The edge processing units 140 may process the data atthe edge network side 110 and send the summarized information to theserver endpoint 310.

For some issue detection logic, the server at the server side 120 maydetermine to collect more data that is not already collected by default.In such scenarios, the server (e.g., servers/services on the server side120 such as the discovery service 160, the cloud control plane 180, or acombination thereof) may detect a subset of clusters 130 which are aprobable list of customers where an issue may be happening. Based on theanalytics, the server can detect a symptom of an issue, but it may notconfirm the issue itself. Once the server detects a list of clusterswhere an issue may be happening based on the symptoms, the server maytrigger an extra data collection from edge processing units 140 forthese systems to confirm the issue. This may be an iterative processwhere the server narrows the subset of the clusters 130 by identifyingthem as having a symptom, collects more data, then repeats moreiterations until all the symptoms have been analyzed. The subset ofclusters who show all the symptoms are determined to have the issue.

Based on any detected symptoms, the server (e.g., the server side 120)can take several different actions. First, the server can enable extradata collection to confirm if the issue exists. In this case, extra datais sent continuously from the edge network side 110, based on thedetected symptom. The server may run analytics on top of the collecteddata to confirm if the issue exists on the cluster. Second, the servermay send a signal to the edge processing units 140 and/or the CFS 150 toexecute workflows to confirm if the issue exists on the HCI clusters 130and/or the edge processing units 140. In this case, the edge processingunits 140 and/or the CFS 150 may execute issue detection logic andresults are sent to the server. The results can be further processed onthe server and are shown to the corresponding customer to takeappropriate actions if applicable.

The server may send instructions to the edge processing units 140 on theedge network side which may run a workflow of rules and take decisionsbased on the result of individual steps in the workflow. The workflowmay include various rules which need to be executed on top of thecluster configurations, logs and metrics. The result of the workflowexecution can detect if an issue is hit on a particular environment ornot.

The server may perform the detection analysis continuously to confirm adetected issue and to detect any changes in the state of the system.Even if according to the current state, the issue does not exist, thestate may change. As such, the server may run the analysis on a clustercontinuously as long as the symptom exists on the cluster. The serveranalysis may detect when the issue is resolved and then stops theanalysis when the symptom is resolved.

Referring still to FIG. 3 , the server side 120 includes aclassification service 340, a recommendation service 350, and arecommendation database (DB) 352. In an exemplary embodiment, theclassification service 340 runs on top of the data repository 330 andcategorizes clusters based on certain feature vectors/classificationparameters. These vectors can be based on a configuration state of theseclusters, such as a number of virtual machines, a software version, ahypervisor type, a number of nodes, etc. The results of thecategorization in the classification service 340 can be fed into arecommendation service 350. In some embodiments, the recommendationservice 350 identifies parameters or the vectors based on which theclusters are dissimilar to each other. This identification may provideinformation regarding the clusters that are similar to each other incertain configuration parameters but differ in certain metrics.

In some embodiments, the recommendation service 350 identifies thedifference in configuration between the two sets of clusters where themetric differs. That difference in configuration can be surfaced as arecommendation to improve the efficiency of the cluster with lowervalues for metrics. Advantageously, employing these classification andrecommendations techniques may solve problems/issues in the virtualizedworkloads in data centers.

The recommendation system can be used to predict issues that are mostlikely to happen to a particular category of clusters. Theclassification service may categorize clusters based on certain featurevectors based on configuration state of these clusters. Then an analysiscan be performed to figure out the various kinds of issues that havebeen identified for a large subset of clusters. The recommendationservice can predict that other clusters which have not yet hit theissues are most likely to run into them. The service can providerecommendations for the other clusters to avoid running into the issue.

In some embodiments, described herein are contextual recommendationsbased on the current and previous state of the state along with thesymptom being detected by the system. This may include cross-customeranomaly detection or cross-customer analytics. As described above, theclassification service 340 may detect various conditions and therecommendation service 350 provides recommendations to the customer toremediate the same.

Contextual recommendations may be based on the current and previousstate of the state along with the symptom being detected by the system.An example of this would be that the customer may have a cluster of VMsboth affected by a particular issue. The discovery engine can recognizethe type of cluster (e.g., a resource type of the cluster such as acompute or storage cluster, a version or type of the cluster managementservice, a version or type of hypervisor, etc.) from the telemetry dataand appropriately select and format.

Each of the components (e.g., elements, entities) of the system 100(e.g., the HCI clusters 130, the edge processing units 140, the CFS 150,the discovery service 160, the user interface 170, the cloud controlplane 180, the edge database 260, the filtering service 270, the serverendpoint 310, the data processing pipeline 320, the data repository 330,the classification service 340, the recommendation service, 350, therecommendation database 352, the pub-sub system 360, the config updateprocessor 410, the original config database 420, the desiredconfiguration database 422, the request database 424, the filteringservice 430, and the RCC 440), is implemented using hardware, software,or a combination of hardware or software, in one or more embodiments.Each of the components of the system 100 may be a processor withinstructions or an apparatus/device (e.g., server) including a processorwith instructions, in some embodiments. In some embodiments, multiplecomponents (e.g., the discovery service 160 and the cloud control plane180) may be part of a same apparatus and/or processor. Each of thecomponents of the system 100 can include any application, program,library, script, task, service, process or any type and form ofexecutable instructions executed by one or more processors, in one ormore embodiments. Each of the one or more processors is hardware, insome embodiments. The instructions may be stored on one or more computerreadable and/or executable storage media including non-transitorystorage media.

Referring now to FIG. 5 , a flowchart of an example method 500 isillustrated, in accordance with some embodiments of the presentdisclosure. The method 500 may be implemented using, or performed by,the system 100, one or more components of the system 100, or a processorassociated with the system 100 or the one or more components of thesystem 100. Additional, fewer, or different operations may be performedin the method 500 depending on the embodiment.

A processor (e.g., the discovery service 160 or the cloud control plane180) identifies a first cluster on an edge network that has an issue anda second cluster on the edge network that has the issue (at operation510). The issue may include a disk failure, high latency, CPU, I/O, ornetwork contention, prevalence of bully VMs, low tolerance orreplication factor, an out-of-date version of a disk firmware,hypervisor, cluster management service, or cluster health service, etc.In some embodiments, the processor is on a cloud server coupled to theedge network. In some embodiments, the processor identifies a firstconfiguration update. In some embodiments, the first configurationupdate is to update a first configuration state (e.g., firstconfiguration settings) of the first cluster to a second configurationstate (e.g., second configuration settings). The processor sends thefirst configuration update to the first cluster (at operation 520). Theprocessor receives feedback from the first cluster (at operation 530).The feedback includes data collected by the edge processing units in thefirst cluster. The feedback may indicate parameters indicating a healthstatus of the first cluster such as latency, IOPS, throughput, CPU, I/O,or network usage, etc.

The processor determines whether the issue is resolved (at operation540). The processor can determine whether the issue is resolved based onthe feedback received from the first cluster. If the processordetermines that the issue is resolved, the processor sends the firstconfiguration update to the second cluster (at operation 550). If theprocessor determines that the issue is not resolved, the processorchanges the first configuration update on the first cluster.Specifically, if the processor determines that the issue is notresolved, the processor determines whether a second configuration updateis available (at operation 560). In some embodiments, the secondconfiguration update is based on the feedback received from the firstcluster.

If the processor determines that the second configuration update isavailable, the processor sends the second configuration update to thefirst cluster (at operation 570). If the processor determines that thesecond configuration update is not available, the processor rollsbacks/reverts, or sends instructions/request to roll back/revert, thefirst configuration update such that the second configuration state ofthe first cluster is returned to the first configuration state that ithad before the first configuration update. In some embodiments, theprocessor performs a remediation action in response to sending the firstconfiguration update, determining that the issue is resolved, ordetermining that the issue is not resolved (e.g., download or install anupdate to a software/firmware, order a new disk to replace the failingdisk, request a new service ticket to be opened, etc.)

Advantageously, the processor uses canary deployment to selectivelyapply configuration settings to clusters that are identified as havingan issue. This is true even though all the clusters have a same softwareversion (including those without the issue). Using canary deployment forconfiguration setting updates without having to update a softwareversion for some or all of the clusters reduces overhead for resourcesand is conducive to scalable edge networks.

Various embodiments disclosed herein are related to a non-transitorycomputer readable storage medium. In some embodiments, the mediumincludes instructions stored thereon that, when executed by a processor,cause the processor to identify a first cluster and a second cluster.

Referring now to FIG. 6 , a flowchart of an example method 600 isillustrated, in accordance with some embodiments of the presentdisclosure. The method 600 may be implemented using, or performed by,the system 100, one or more components of the system 100, or a processorassociated with the system 100 or the one or more components of thesystem 100. Additional, fewer, or different operations may be performedin the method 600 depending on the embodiment. In some embodiments, oneor more operations of the method 600 are combined with one or moreoperations of at least one of the method 500.

A processor (e.g., the CFS 150) on an edge network detects aconfiguration state change of a cluster including one or more edgeprocessing units. In some embodiments, the state change includes atleast one of adding a node, or upgrading a software, or a change inhealth status (e.g., detecting a failure of a disk) (at operation 610).The processor identifies a plurality of first configuration overriderules from a first source and a plurality of second configurationoverride rules from a second source (at operation 620). For example, theprocessor receives the first configuration override rules from servicesin the cluster and the second configuration override rules from thecloud (e.g., the server side 120). In some embodiments, the plurality offirst configuration override rules are conflicting with the plurality ofsecond configuration override rules. For example, the plurality of firstconfiguration override rules may specify a first rate (e.g., frequency)at which an edge processing unit is to collect data and a first type ofdata to collect, whereas the plurality of second configuration overriderules may specify a second rate at which an edge processing unit is tocollect data and a second type of data to collect.

The processor merges at least one first configuration override rule withat least one second configuration override rule to generate a pluralityof third configuration override rules (at operation 630). For example,the processor may merge the first configuration override rule thatspecifies the first rate at which the edge processing unit is to collectdata and the second type of data to collect. In some embodiments, themerge is on a rule-by-rule basis. For example, the rate of datacollection is a first rule that includes multiple parameters including(a) whether to check for CPU and memory usage, (b) whether to flagerrors, and (c) whether to send flags to the cloud. Thus, the merge isperformed on the first rule by combining different parameters. Thisprocess can be repeated for all rules of a subsystem/service (e.g.,cluster health check service) or all the services of a cluster. In someembodiments, the processor defers to the configuration override rulesreceived from the cloud. In some embodiments, the processor selects themost conservative configuration update (e.g., a highest rate at which tocollect operational data from the services of the cluster).

The processor updates a configuration of the edge processing using theplurality of third configuration override rules (at operation 640). Theprocessor collects data from the edge processing units in accordancewith the configuration update (at operation 650). The processor sendsthe data to a server coupled to the edge network (at operation 660). Insome embodiments, the server receives the data for further processing.In some embodiments, the server determines an action based on the statechange (e.g., send another configuration update, send a new version ofsoftware to the cluster on the edge as part of an upgrade, order a newdisk to replace the failing disk, open a new service ticket, etc.).

In some embodiments, the processor monitors the edge processing units.In some embodiments whether the configuration update causes an issue(e.g., an increase in latency, a decrease in throughput, an increase inCPU, I/O, or network consumption, etc.). In some embodiments, upondetermining that the configuration update causes an issue, the processorinitiates a rollback of the configuration state, independent of thecloud.

Various embodiments disclosed herein are related to a non-transitorycomputer readable storage medium. In some embodiments, the mediumincludes instructions stored thereon that, when executed by a processor,cause the processor to detect, on an edge network, a state change of acluster including one or more edge processing units, identify aplurality of first configuration override rules from a first source anda plurality of second configuration rules from a second source, merge atleast one first configuration override rule with at least one secondconfiguration override rule to generate a plurality of thirdconfiguration override rules, update a configuration of the one or moreedge processing units using the plurality of third configurationoverride rules, and collect data from the one or more edge processingunits in accordance with the configuration update.

In some embodiments, the first source is a service within the clusterand the second source is a cloud server coupled to the edge network. Insome embodiments, at least a third configuration override rule of theplurality of first configuration override rules is conflicting with atleast a fourth configuration override rule of the plurality of secondconfiguration override rules.

In some embodiments, the medium further includesinstructions stored thereon that, when executed by the processor, causethe processor to defer to a fifth configuration override rule from acloud server coupled to the edge network to determine which of the thirdconfiguration override rule and the fourth the third configurationoverride rule to include in the plurality of third configurationoverride rules.

In some embodiments, the medium further includes instructions storedthereon that, when executed by the processor, cause the processor to, inresponse to updating the configuration, perform at least one of sendinganother configuration update, sending a new version of software to thecluster as part of an upgrade, ordering a new disk to replace a failingdisk, or opening a new service ticket.

Referring now to FIG. 7A, a flowchart of an example method 700 isillustrated, in accordance with some embodiments of the presentdisclosure. The method 700 may be implemented using, or performed by,the system 100, one or more components of the system 100, or a processorassociated with the system 100 or the one or more components of thesystem 100. Additional, fewer, or different operations may be performedin the method 700 depending on the embodiment. In some embodiments, oneor more operations of the method 700 are combined with one or moreoperations of at least one of the methods 500-600.

A processor (e.g., the filtering service 430, the pub-sub system 360, ora combination thereof), on a server, receives, from a cluster, aconfiguration state (e.g., a current configuration state) of thecluster, such as an HCI cluster 130, on an edge network (at operation710). The processor maps the configuration state to a list of streams(at operation 720). For example, the configuration state may includemultiple configuration (e.g., filtering) parameters, and every parametermaps to a stream. Parameters can include number of nodes, hypervisortype, hypervisor version, cluster management service version, clusterhealth check service version, or other software or hardware parametersof the cluster configuration, some of which are described above. In someembodiments, the mapping is in a data structure stored in memory orstorage (e.g., non-transitory storage medium).

The processor sends the list of streams to the cluster (at operation730). The processor receives an indication that the cluster subscribedto the list of streams (at operation 740). The processor determineswhether a configuration update for one of the list of streams isavailable (e.g., released, identified, etc.) (at operation 750). If theprocessor determines that the configuration update is not available, themethod 700 returns to operation 750. If the processor determines thatthe configuration update is available, the processor sends theconfiguration update to the cluster (e.g., the processor publishes/sendsthe configuration update on/via the one of the list of streams) (atoperation 760). The processor determines whether the configuration statechanges (at operation 770). In some embodiments, the configuration statechange includes adding a node, upgrading a software, health statuschange (e.g., detecting a failure of a disk), or a status for canarydeployment (e.g., a cluster is selected for receiving and applying aconfiguration update to see if the update is effective in resolving anissue).

If the configuration state changes, the method 700 returns to operation720. If it does not, the method returns to operation 750 (e.g.,continuously/periodically every predetermined interval check if theconfiguration state has changed). In some embodiments, the cluster(e.g., one or more nodes on the cluster) applies the configurationupdate. In some embodiments, the processor performs a remediation actionin response to the configuration update (e.g., send anotherconfiguration update, send a new version of software to the cluster onthe edge as part of an upgrade, order a new disk to replace the failingdisk, open a new service ticket, etc.)

As described above, the server provides a list of streams (as opposed toone stream) for subscription based on a configuration state (e.g.,configuration settings) of a cluster. Advantageously, processing isoffloaded from the server because the server does not have to evaluatewhich clusters or nodes are to receive an update each time the updatebecomes available. Thus, the method 700 enables a scalable edge network.Moreover, the subscription is dynamic and can change whenever thecluster has a configuration state change.

Additional, fewer, or different operations may be performedin the method 701 depending on the embodiment. In some embodiments, oneor more operations of the method 701 are combined with one or moreoperations of at least one of the methods 500-700.

A processor (e.g., the filtering service 270) receives, on a node of acluster, an indication that a configuration update has been received bythe cluster (at operation 711). In some embodiments, the configurationupdate is received by a cluster configuration client, such as the CFS150. The processor compares a first parameter (e.g., a type and valuethereof) of a configuration state to a second parameter (e.g., a typeand value thereof) of the configuration update (at operation 721). Insome embodiments, (e.g., a type of) at least one of the first parameteror the second parameter includes number of nodes, hypervisor type,hypervisor version, cluster management service version, cluster healthcheck service version, or other software or hardware parameters of thecluster configuration. The processor determines if the first parameter(e.g., value of the first parameter) matches the second parameter (e.g.,value of the second parameter) (at operation 731). For example, theprocessor determines that the configuration state includes a hypervisorof a first type, whereas the processor the configuration update is for ahypervisor of a second type. In one aspect, for a type of a parameterincludes a hypervisor type, a corresponding value of the parameter mayinclude type-1 hypervisor, type-2 hypervisor, Nutanix AcropolisHypevisor (AHV), Elastic Sky X (ESX), or the like.

Referring now to FIGS. 8A-8B, a flowchart of an example method 800 isillustrated, in accordance with some embodiments of the presentdisclosure. The method 800 may be implemented using, or performed by,the system 100, one or more components of the system 100, or a processorassociated with the system 100 or the one or more components of thesystem 100. Additional, fewer, or different operations may be performedin the method 800 depending on the embodiment. In some embodiments, oneor more operations of the method 800 are combined with one or moreoperations of at least one of the methods 500-701.

A processor (e.g., the discovery service 160, the user interface 170,the RCC 440, or a combination thereof) detects an indication to collectadditional data on a cluster of an edge network (at operation 805). Insome embodiments, the processor detects an indication to collectadditional data based on determining that a cluster has an issue (e.g.,detection of the issue is the indication that additional data isneeded). In some embodiments, the indication specifies that theadditional data is to be sent to the server for further processing. Theprocessor sends, to the cluster, a command to receive a command outputincluding the collected additional data (at operation 810).

The processor determines whether there is an indication to collect rawdata or parsed data (at operation 815). The processor may determine thetype of data needed (e.g., raw data or parsed data) based on theindication to collect additional data. For example, if the processordetermines that a name of a VM is needed, raw data can be sent, whereasif the processor determines that a report of which nodes powered on inthe last 7 days is needed, parsed data should be sent to reduce networkI/O and processing on the server side.

The processor indicates to the cluster to send the type of data. If theprocessor determines that there is an indication to collect raw data,the processor sends, to the cluster, a parsing command indicating that acommand output is to be parsed on the edge side (at operation 820). Insome embodiments, not sending a parsing command within a predeterminedtime period of sending the command indicates to the cluster to send thecommand output as raw data. The processor receives at least a portion ofthe command output in accordance with the command (at operation 825).

The processor determines whether the command output is chunked (e.g.,chunkified, split, partitioned, separated into data units, etc.) (atoperation 830). In some embodiments, the cluster (e.g., a node on thecluster) decides whether to chunk the command output. In someembodiments, if the command output exceeds the limit, the cluster sendsthe command output as one or more chunked file uploads, but if thecommand output is less than the limit, the cluster sends the commandoutput as one packet (e.g., HTTP request packet). If the processordetermines that the command output is chunked, the processor determineswhether all of the chunks constituting the command output have beencollected (at operation 835). If the processor determines that all ofthe chunks are not collected, the processor receives a second chunk (atoperation 840) and the method 800 returns to operation 835. This looprepeats until all of the chunks are collected. If the processordetermines that all of the chunks are collected, the processoraggregates the chunks (at operation 845). The processor troubleshoots anissue of the cluster based on the command output (at operation 850). Insome embodiments, responsive to troubleshooting the issue, the processorperforms a remediation action (e.g., send another configuration update,send a new version of software to the cluster on the edge as part of anupgrade, order a new disk to replace the failing disk, open a newservice ticket, etc.).

Additional, fewer, or different operations may be performedin the method 900 depending on the embodiment. In some embodiments, oneor more operations of the method 900 are combined with one or moreoperations of at least one of the methods 500-800.

A processor (e.g., a discovery service such as the discovery service160, a cloud control plane such as the cloud control plane 180, or acombination thereof) detects, on a server, a first symptom observable ona first one or more clusters of an edge network (e.g., HCI clusters 130or nodes therein) (at operation 910). The first symptom is indicative ofan issue. For example, the processor detects that a customer is not ableto write data, such that the first one or more clusters are all theclusters owned by that customer. The processor may determine thisinformation based on data that is regularly (e.g., previously) collectedand/or processed at the edge network. The processor triggers additionaldata collection for the one or more first clusters (at operation 920).For example, the processor triggers collection of one or more of I/O(input/output) stack of the disk, hardware information of the disk(version, firmware), a lifespan of disk, hardware and softwarediagnostics, or other information about each of the clusters.

From the first one or more clusters, the processor determines, based onthe additional data collected, a second one or more clusters (e.g., thatis a part of the first one or more clusters) that have a second symptomindicative of the issue (at operation 930). The second symptom may belatency exceeding a threshold, a version of a software, or a type ofhypervisor. The processor determines whether there are any more (e.g.,related) symptoms indicative of the issue (at operation 940). If thereare more symptoms, the method 900 returns to the operation 920 for thenext symptom(s) and repeats until a third one or more clusters that haveeach of the symptoms indicative of the issue are determined. The secondone or more clusters include the third one or more clusters. Theprocessor generates a remediation action for the third one or moreclusters (at operation 950). In some embodiments, the remediation actionincludes one or more of sending a new disk to the customers associatedwith the subset of clusters, running/sending a configuration update,manually intervening to correct the issue, or creating a service ticket.

The processor receives data (either as part of regular data collectionor as a part of the additional data collection) from the third one ormore clusters (at operation 960). The processor determines, based on thereceived data, whether the issue is resolved (at operation 970). If theissue is not resolved, the method 900 returns to the operation 950 togenerate another remediation action and repeats until the issue isresolved. In some embodiments, if the issue is not resolved, the method900 returns to operation 920.

A processor (e.g., the classification service 340, the recommendationservice 350, or a combination thereof) classifies clusters/nodes basedon one or more classification parameters (e.g., feature vectors) (atoperation 1010). The processor detects, within the plurality ofclusters, one or more affected clusters having an issue (at operation1020). The processor determines classification parameter values of theaffected clusters (e.g. at least one of affected clusters or affectednodes) (at operation 1030). For example, the issue may be a bad disk.Classification parameters may include one or more of the I/O per second(IOPS), the number of nodes in the cluster, the version/type of firmwareof the disk, or the model of the disk. The classification parameters mayindicate one or more of that the affected clusters/nodes are on I/Ointensive clusters, on bigger clusters, with a specific firmware, or aspecific model of disk.

The processor determines other clusters that have the classificationparameter values or other values that are within a predeterminedamount/percentage of the classification parameter values (at operation1040). For example, the IOPS or number of nodes fall in the range of theaffected clusters/nodes and the firmware and model of disk are the same.The processor generates a remediation action or an instruction toperform a remediation action (e.g., recommendation) (at operation 1050).The processor sends an instruction for a remediation action to the otherclusters (e.g., instructs the other clusters to download or install anupdate to a software/firmware, order a new disk to replace the failingdisk, request a new service ticket to be opened, etc.) or performs theremediation action on behalf of the one or more other clusters (e.g.,send another configuration update, send a new version of software to thecluster on the edge as part of an upgrade, order a new disk to replacethe failing disk, open a new service ticket, etc.) (at operation 1060).In some embodiments, the processor sends the remediation action to theaffected clusters and the other clusters or performs the remediationaction on behalf of the affected clusters and the other clusters. If theother clusters receive the instruction, the other clusters can perform aremediation action based on the instruction.

Advantageously, the method 1000 can detect, predict, and/or correctissues on other clusters that are heuristically related to affectedclusters on which issues have already been detected, even if theaffected clusters and the other clusters are not physical related. Forexample, in some embodiments, the affected clusters and other clustersare in separate datacenters and/or geographies. In one aspect, theaffected clusters can be in a first datacenter in a first geographicregion/zone (e.g., Western United States, United States, etc.) and theother clusters can be in a second datacenter in a second geographicregion/zone (e.g., Eastern United States, India, Etc.) In someembodiments, the affected clusters and other clusters are not connectedto a same hypervisor, and not connected to a same switch.

In some embodiments, the classification service classifies a parametersuch as a version of a cluster management software. The recommendationservice identifies clusters that are using an unacceptably old (olderthan a predetermined threshold) or a faulty version (e.g., a versionthat has IOPS below a predetermined threshold). The recommendationservice can send a recommendation to those who are running the old orfaulty version. In some embodiments, the recommendation is dependent oncontext. For example, the customer of the cluster may require the olderversion of the service or may have a policy that caps the IOPS of theservice.

The herein described subject matter sometimes illustrates differentcomponents contained within, or connected with, different othercomponents. It is to be understood that such depicted architectures aremerely exemplary, and that in fact many other architectures can beimplemented which achieve the same functionality. In a conceptual sense,any arrangement of components to achieve the same functionality iseffectively “associated” such that the desired functionality isachieved. Hence, any two components herein combined to achieve aparticular functionality can be seen as “associated with” each othersuch that the desired functionality is achieved, irrespective ofarchitectures or intermedial components. Likewise, any two components soassociated can also be viewed as being “operably connected,” or“operably coupled,” to each other to achieve the desired functionality,and any two components capable of being so associated can also be viewedas being “operably couplable,” to each other to achieve the desiredfunctionality. Specific examples of operably couplable include but arenot limited to physically mateable and/or physically interactingcomponents and/or wirelessly interactable and/or wirelessly interactingcomponents and/or logically interacting and/or logically interactablecomponents.

With respect to the use of substantially any plural and/or singularterms herein, those having skill in the art can translate from theplural to the singular and/or from the singular to the plural as isappropriate to the context and/or application. The varioussingular/plural permutations may be expressly set forth herein for sakeof clarity.

It will be understood by those within the art that, in general, termsused herein, and especially in the appended claims (e.g., bodies of theappended claims) are generally intended as “open” terms (e.g., the term“including” should be interpreted as “including but not limited to,” theterm “having” should be interpreted as “having at least,” the term“includes” should be interpreted as “includes but is not limited to,”etc.). It will be further understood by those within the art that if aspecific number of an introduced claim recitation is intended, such anintent will be explicitly recited in the claim, and in the absence ofsuch recitation no such intent is present. For example, as an aid tounderstanding, the following appended claims may contain usage of theintroductory phrases “at least one” and “one or more” to introduce claimrecitations. However, the use of such phrases should not be construed toimply that the introduction of a claim recitation by the indefinitearticles “a” or “an” limits any particular claim containing suchintroduced claim recitation to disclosures containing only one suchrecitation, even when the same claim includes the introductory phrases“one or more” or “at least one” and indefinite articles such as “a” or“an” (e.g., “a” and/or “an” should typically be interpreted to mean “atleast one” or “one or more”); the same holds true for the use ofdefinite articles used to introduce claim recitations. In addition, evenif a specific number of an introduced claim recitation is explicitlyrecited, those skilled in the art will recognize that such recitationshould typically be interpreted to mean at least the recited number(e.g., the bare recitation of “two recitations,” without othermodifiers, typically means at least two recitations, or two or morerecitations). Furthermore, in those instances where a conventionanalogous to “at least one of A, B, and C, etc.” is used, in generalsuch a construction is intended in the sense one having skill in the artwould understand the convention (e.g., “a system having at least one ofA, B, and C” would include but not be limited to systems that have Aalone, B alone, C alone, A and B together, A and C together, B and Ctogether, and/or A, B, and C together, etc.). In those instances where aconvention analogous to “at least one of A, B, or C, etc.” is used, ingeneral such a construction is intended in the sense one having skill inthe art would understand the convention (e.g., “a system having at leastone of A, B, or C” would include but not be limited to systems that haveA alone, B alone, C alone, A and B together, A and C together, B and Ctogether, and/or A, B, and C together, etc.). It will be furtherunderstood by those within the art that virtually any disjunctive wordand/or phrase presenting two or more alternative terms, whether in thedescription, claims, or drawings, should be understood to contemplatethe possibilities of including one of the terms, either of the terms, orboth terms. For example, the phrase “A or B” will be understood toinclude the possibilities of “A” or “B” or “A and B.” Further, unlessotherwise noted, the use of the words “approximate,” “about,” “around,”“substantially,” etc., mean plus or minus ten percent.
